A ray of light is incident at an angle of `30^(@)` with the plane of a plane mirror. Find the angle of reflection.

Explanation

To solve the problem, we need to determine the angle of reflection when a ray of light strikes a plane mirror at an angle of \(30^\circ\) with respect to the plane of the mirror.

### Step-by-Step Solution:

1. **Understanding the Geometry**:
- The angle of incidence is measured from the normal to the surface of the mirror. Since the ray is incident at \(30^\circ\) with respect to the plane of the mirror, we first need to find the angle of incidence with respect to the normal.

2. **Finding the Angle of Incidence**:
